本发明提出一种微波烹饪器具。
微波烹饪器具是一种通过微波烹饪食物的厨房电器，微波发生装置与供电电源装置相连，产生微波，经波导馈入微波烹饪器具的腔体中，对食物进行加热。在一种异形微波烹饪器具中，腔体为圆柱形，改善了传统的方形微波烹饪器具中加热效率低和不均匀的问题。
在本发明实施例中，如图1和图2所示，该微波烹饪器具包括腔体1、微波发生装置3、用于给微波发生装置3供电的供电电源装置2和波导4，腔体1的内腔为圆柱形，供电电源装置2和微波发生装置3设置于腔体1的侧面，腔体1设置有微波馈入口132，波导4连接微波发生装置3和微波馈入口132。微波烹饪器具的腔体1为放置食物的烹饪腔，供电电源装置2的作用是提供电压合适的直流电，以供微波发生装置3产生微波。当微波发生装置3为半导体微波发生器时，供电电源装置2为直流电源模块，提供32 V的低压直流电；当微波发生装置3为磁控管时，供电电源装置2为变频器或变压器，提供高压直流电。微波发生装置3产生的微波经波导4传输至腔体1上的微波烹饪器具馈入口132，并由微波馈入口132馈入腔体1。
腔体1可设计为不同的形状，本实施例中，腔体1的内腔11为圆柱形，敞口开设在顶部。圆柱形内腔11有利于微波的均匀分布和损耗的减少，从而实现均匀和高效的加热。将腔体1的敞口开设在顶部，方便食物的取放，且工艺相比将敞口开设在圆柱形内腔11侧面的工艺更简单。供电电源装置2和微波发生装置3设置于腔体1的侧面，有多种排布方式。如图1所示，在腔体1本身的高度足够的情况下，供电电源装置2和微波发生装置3竖直叠放在腔体1外侧，以减小微波烹饪器具的横向尺寸。如图2所示，供电电源装置2和微波发生装置3水平排列在腔体1外侧。如图3所示，供电电源装置2和微波发生装置3水平排列，围绕在腔体1外周，以更充分地利用微波烹饪器具的横向空间，避免微波烹饪器具整体在某一水平方向上的尺寸过大。上述排布方式将在后文中详细阐述。微波馈入口132可以设置在腔体1的侧面或底面，并根据微波发生装置3和微波馈入口132的相对位置，设计相应的波导4的结构，以将微波发生装置3产生的微波从微波馈入口132馈入腔体1中。当微波馈入口132设置在腔体1的侧面时，由于是弧面，因此波导4应包括与腔体1的侧面相适配的弧状微波出口42，这将导致波导4的加工工艺更复杂。为了简化波导4的结构，降低制造过程中的工艺复杂度和传输过程中的微波损耗，可将微波发生装置3设置在靠近腔体1且偏下的位置，将微波馈入口132设置在腔体1的底面，通过直波导4传输微波。供电电源装置2和微波发生装置3可设置于独立于腔体1的支撑部上，也可设置于与腔体1一体的安装部上。
在本发明的一优选实施例中，如图1、图4和图5所示，腔体1上设有顶板12和底板13，顶板12的一侧与内腔11的上端相连，另一侧设有用以安装供电电源装置2和第一风扇51的第一安装部121，底板13的一侧与内腔11的下端相连，另一侧设置有用以安装微波发生装置3和第二风扇52的第二安装部131。顶板12和底板13的边缘相平齐，以优化微波烹饪器具装配空间的分布。在一具体方案中，顶板12和底板13为一边为半圆弧的矩形板，顶板12和底板13的半圆端连接在内腔11上，矩形端形成供电电源装置2和微波发生装置3的安装部。第一安装部121和第二安装部131为矩形开口，供电电源装置2和微波发生装置3等电气组件通过螺钉固定其中。为了简化波导4的结构，减少微波损失，降低工艺复杂度，供电电源装置2设置于上方的第一安装部121中，微波发生装置3设置于下方的第二安装部131中。
微波烹饪器具还包括正对供电电源装置2和微波发生装置3设置的风扇。由于供电电源装置2和微波发生装置3在工作过程中的产热量较大，因此需要风扇对其进行散热。风扇可以设置于供电电源装置2和微波发生装置3的上方、下方或侧面，正对供电电源装置2和微波发生装置3吹风或排风，以增大热空气的流动性，风扇的设置位置与微波烹饪器具的整体装配空间相适应。在本实施例中，风扇包括第一风扇51和第二风扇52，第一风扇51设置于供电电源装置2的侧面，第二风扇52设置于微波发生装置3的侧面。由于微波发生装置3相对供电电源装置2的产热量更大，分别设置风扇一方面增大了散热量，另一方面可根据不同的散热要求调整风扇的运行转速或运行时间，以实现低功耗、高效率的散热。如图1所示，第一风扇51和供电电源装置2设置于第一安装部121中，第二风扇52和微波发生装置3设置于第二安装部131中，可通过螺钉紧固。
如图5所示，微波馈入口132设置于腔体1的底面。根据腔体1底面的组件排布情况和微波耦合效率的要求，确定微波馈入口132的形状。本实施例中，微波馈入口132为腔体1的底面中心的矩形孔，设置在底面中心有利于微波在腔体1中的均匀分布。
相应的，波导4为直波导，通过焊接方式与微波烹饪器具的腔体1相连。如图6所示，波导4的顶面两端分别设置有微波入口41和微波出口42，其中，微波入口为孔径22 ~ 30毫米的圆孔，与微波发生装置3的微波输出口31相对接，以实现较高的微波耦合效率，使产生的微波尽量输送至波导4中。微波发生装置3的微波输出口31插入微波入口42中，直波导的顶面还设置有螺孔44，与微波发生装置螺孔32通过螺钉相连。微波出口42可以为矩形、圆形、平行四边形或其它不规则形状，与微波馈入口132相对接。考虑到本实施例中的微波馈入口132为底面中心的矩形孔，因此微波出口42为与之相适配的矩形。直波导为长度240 ~ 260 毫米，宽度75 ~ 85毫米的封闭金属腔，微波在通道43中多次反射，被输送至微波馈入口132。
如图1和图4所示，微波烹饪器具还包括设置于腔体1的顶部，封闭腔体1的顶部敞口的炉门6。炉门6为圆形板状，与腔体1的顶部敞口相适配，炉门6通过安装槽61与腔体1相卡合，封闭腔体1，并设置有轭流槽62，以进一步抑制微波在炉门6和腔体1接缝处的泄漏。
在本发明的另一实施例中，如图2所示，供电电源装置2和微波发生装置3水平排列于腔体1的侧面。腔体1包括内腔11和底板13，底板13连接于腔体1的下方。底板13包括第二安装部131，供电电源装置2和微波发生装置3可通过螺钉固定于第二安装部131。在一具体方案中，为了简化波导4的结构，微波发生装置3位于靠近腔体1的位置，供电电源装置2相对远离腔体1。微波馈入口132设置于腔体1的底面上，波导4为直波导，连接微波发生装置3和微波馈入口132，其具体的尺寸和连接方式可参考上一实施例中所阐述的。
本实施例中，由于供电电源装置2和微波发生装置3水平排列，可设置一个风扇进行散热，也可设置第一风扇和第二风扇分别散热。在一具体方案中，风扇通过第二安装部固定于供电电源装置2和微波发生装置3的侧面。在另一具体方案中，如图5所示，腔体1包括顶板12，顶板12上设置有第一安装部121，风扇可通过螺钉固定于第一安装部121，设置于腔体1 的侧面、供电电源装置2和微波发生装置3的上方，以实现散热。
在本发明的又一实施例中，如图6所示，供电电源装置2和微波发生装置3水平排列，围绕在腔体1外周。该设置方式可避免上一实施例的设置方式导致的微波烹饪器具整体在某一水平方向上的尺寸过大。微波馈入口设置于腔体1的底面，波导4为直波导，连接微波发生装置3和微波馈入口。同理，第一风扇和第二风扇可分别设置于供电电源装置2和微波发生装置3的侧面或上方，通过螺钉固定在第二安装部131上或顶板12的第一安装部121上。
本发明技术方案的微波烹饪器具，包括腔体、微波发生装置、用于给微波发生装置供电的供电电源装置和波导，腔体的内腔为圆柱形，供电电源装置和微波发生装置设置于腔体的侧面，腔体设置有微波馈入口，波导连接微波发生装置和微波馈入口，通过将微波烹饪器具的包括供电电源装置和微波发生装置的电气组件设置于腔体侧面，有效降低了微波烹饪器具整体的高度，从而提高了操作的方便性。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
